For the last few days I have had intermittent discomfort/mild cramping/aching on the right side of my abdomen, at waist line. This discomfort is on my side, so includes a little to the front and to the back. Occurrence follows eating (not large amount) by about an hour. No particular food or time of day. It feels like a muscle cramp, and I react by wanting to bend over to the right. Doesn t help. Sitting can make it worse; lying down helps. I do not have a gallbladder or an appendix; have had a colonoscopy under one year ago. Have had IBS for many, many years; it is usually under control.
